Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine – a pit, and the ...

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
performed an estimation of the remaining and available resources of the Pittsburgh (No. 8) coal bed in Ohio. This study represents the first statewide estimation of Pittsburgh coal resources in 14 years. The Pittsburgh (No. 8) coal is the most heavily mined coal bed in Ohio, representing 64 percent of the total coal mined within the state.
tested to extract coal from thick seams and to mine steeply dipping seams at two mines with Federal leases in Colorado—the Coal Basin Complex of Midcontinent Resources and the Snowmass Mine of Snowmass Coal Co. These projects are likely to encourage the use of longwall mining to extract other thick or steeply pitching coal seams in the area.
Mining operations must improve efficiency and quality from exploration through processing in order to ensure profitability. From mineral analysis to complete bulk weighing, monitoring, and sampling systems, to informatics, you will find the latest equipment and technology for your mineral and metals, coal, cement, or oil and gas exploration and mining operations.

"The first priority and concern of all in the coal or mining industry must be the health and safety of our most precious resource, the miner." (Federal Coal Mine Health and Safety Act of 1969, amended 1977) The NIOSH Coal Workers'' Health Surveillance Program (CWHSP) studies the causes and ...
Coal mining is only a temporary use of land, so it is vital that rehabilitation of land takes place once mining operations have stopped. In best practice a detailed rehabilitation or reclamation plan is designed and approved for each coal mine, covering the period from the start of operations until well after mining .
involved in making such an estimate. The exact quantity of coal resources is not known. We cannot predict what improvements will be made in mining technology that would allow the recovery of more of the coal than is currently achieved. We cannot evaluate with certainty what tolerance coal consumers might have for using coal of lower quality than is
The Centralia Coal Mine, in County, was once Washington''s largest coal mine. Production came from five coal beds within the Skookumchuck Formation. It closed down production in 2006. The John Henry Mine, located in the Black Diamond Coal Field, produced about 250,000 tons per year during the mid1990s and closed in 1997.
